Initial house was 2000 square feet and have one 5 ton Trane. House was extended to 5500 square feet and 4 condensers were added. The Trane condenser no longer works and must replace it. I have a couple of questions since this 5 ton Trane only cools about 1300 square feet now, can I get a smaller consdenser? Companies have said that I could only go as low as 4 tons if I am not also replacing the air handler...
I live on Long Island.
One company would want to replace the condenser with a new 4 ton trane, the second company wants to replace it with a 4 ton American Standard (for about $1000 less) and the third company would replace it with a 4 ton Maratherm for a little less than the second company.
Which do you think is the best option?
